Abstract

The paper presents the results of research on the formation of complex hybrid populations, an assessment of the collection samples of clover on a complex of economically valuable traits for the creation of forage varieties. The basis for the study were promising plants that weresown in a wide row and individually in a row. By negative selection, weak and underdeveloped plants were mowed down. It`s been noticed that there was the direct dependence of clover seeds` creation from the weather conditions. The collection samples of meadow clover`s assessment was given according to the complex of economically valuable features for the creation of the hay –pasture type varieties. The best samples are allocated for the yield of the green mass, the plants` height. The initial material was obtained on the signs of adaptability, yield of green mass, foliage and seed productivity. Promising clover samples were selected for high seed productivity, reaching more than 60 %. Similarly, in accordance with the vertical zonality of the natural habitats of wild introducers, the protein content in plant samples also increases. In terms of fodder yield, the maximum indicators were noted in the varieties Farn, Ustodlivy (Belorussian selection), Orlik (All-Russian Scientific Research Institute of Legumes and Millet Crops), complex hybrid populations that exceeded the standard – the Daryal variety by 12-25%. According to seed, Nart varieties were distinguished. Synthetic populations Syn 305-03, Syn 274-94 (selection SKNIIGPSH VNC RAS), FM-143(VNII kordov), Dargavsky, (wild specimen of RSO – Alanya).
